Do not leave boards exposed to prolonged rain before the roof covering is installed.Frequently asked questionsHow many sheets do I need?Calculate the total area in m² and divide by 1.49 (area per sheet). Add 10–15% for cutting waste on hip and gable roofs. Round up to the nearest whole sheet.What fixings should I use?50–65mm ring-shank galvanised nails or coarse-thread roofing screws. Ring-shank nails provide better pull-through resistance in Mauritius’s high-wind and cyclone-prone conditions.Is this board suitable for Mauritius’s climate?Yes. The WBP glue bond is designed for exterior and humid conditions. Install underlayment or sisalation as soon as possible after fixing, and seal all edges in coastal or high-humidity locations.
